ApexSQL Search installation problem - "Failed to load .NET Framework DLL"

Hi,

Can anybody help - while trying to install ApexSQL Search error comes:

"C:\Program Files\ApexSQL\ApexSQL

Search\DevExpress.Data.vl9.2.dll

Internal error: Failed to load .NET Framework DLL "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Fusion.dll"

Click Retry to try again, Ignore to skip this file (not recommended), or Abort to cancel installation"

Uninstalled and installed back .net but still no improvement, downloaded ApexSQL Search twice, the same.
